lstseq.greedy {delt} | R Documentation |

## Calculates a scale of greedy histograms

### Description

Calculates a scale of greedy histograms.
The histograms in the scale have a partition of growing cardinality.
Returns a sequence of estimates as piecewise constant functions and
optionally as level set trees.
Optionally a shape tree for a level set of each estimate is calculated.

### Usage

lstseq.greedy(dendat, maxleaf, lstree = NULL, level = NULL)

### Arguments

`dendat` |
n*d data matrix |

`maxleaf` |
integer>1; the scale consists of histograms whose
partitions have cardinality 1,...,maxleaf |

`lstree ` |
if NULL, then level set trees are not calculated |

`level` |
if NULL, then shape trees are not calculated;
if positive number, then it is
the level of the level sets for which the shape trees are calculated |

### Value

A list with components

`lstseq` |
a list of level set trees |

`pcfseq` |
a list of piecewise constant functions |

`stseq` |
a list of shape trees |

`hseq` |
a vector of smoothing parameters corresponding to the members
in the sequences;
the smoothing parameter is the cardinality of the partition |
